This model is not associated with Triumph motorcycles and is meant to be a temporal replacement while the original (if exists) is found. Unfortunately it seems that left control for the motorcycle is sold as a whole, and the turn signal cover cannot be purchased separately, hence I designed this replacement part.
I designed this part using an original part as a guide to ensure best fitment and tested on a real motorcycle.
I printed the final version in ASA although you could use ABS or another material intended for exterior use.
The author marked this model as their own original creation.
